Electronic device and operating method thereof

ABSTRACT

An electronic device and an method of operating the same according to various example embodiments of the present disclosure are provided. The method may include: receiving, by first image reception circuitry of a first image reception unit, first image data corresponding to a first attribute parameter; receiving, by second image reception circuitry of a second image reception unit, second image data corresponding to a second attribute parameter; detecting converted image data from the first image data based on a difference in component between the first attribute parameter and the second attribute parameter; and generating compressed image data for the second image data using the converted image data.

CROSS-REFERENCE TO RELATED APPLICATION

This application is based on and claims priority under 35 U.S.C. § 119 to Korean Application Ser. No. 10-2015-0167381, which was filed in the Korean Intellectual Property Office on Nov. 27, 2015, the disclosure of which is incorporated by reference herein in its entirety.

TECHNICAL FIELD

The present disclosure relates generally to an electronic device and an operation method thereof.

BACKGROUND

With the development of technology, an electronic device may be provided with various functions to perform complex functions. The electronic device may include a camera unit. In addition, the electronic device may photograph image data through the camera unit. Recently, the camera unit is implemented by a dual camera structure so as to photograph dual image data. In other words, the camera unit may acquire first image data and second image data. Here, the first image data and second image data may be symmetrical to each other. In addition, the camera unit may individually compress the first image data and second image data. Accordingly, the electronic device may individually store the first image data and second image data. In addition, the electronic device may synthesize the first image data and second image data.

However, in the electronic device as mentioned above, there is a problem in that the storage size for dual image data increases. The problem may occur due to the fact that the electronic device independently stores first image data and second image data. In addition, when the first image data and the second image data are asymmetrical to each other, there may be a difficulty in that the camera unit compresses the first image data and second image data. This may occur due to the fact that the camera unit compresses the first image data and second image data in the same compression scheme. Accordingly, the processing efficiency of the dual image data in an electronic device may be lowered.

SUMMARY

An electronic device according to various example embodiments may include: first image receiving circuitry configured to receive first image data corresponding to a first attribute parameter; second image receiving circuitry configured to receive second image data corresponding to a second attribute parameter; image conversion circuitry configured to detect, from the received first image data, converted image data based on a difference in component between the first attribute parameter and the second attribute parameter; and image compression circuitry configured to generate compressed image data for the received second image data using the converted image data.

An method of operating an electronic device according to various example embodiments may include: receiving first image data corresponding to a first attribute parameter and second image data corresponding to a second attribute parameter; detecting converted image data from the received first image data based on a difference in component between the first attribute parameter and the second attribute parameter; and generating compressed image data for the received second image data using the converted image data.

DETAILED DESCRIPTION

Hereinafter, various example embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that there is no intent to limit the present disclosure to the particular forms disclosed herein; rather, the present disclosure should be construed to cover various modifications, equivalents, and/or alternatives of embodiments of the present disclosure. In describing the drawings, similar reference numerals may be used to designate similar constituent elements.

As used herein, the expression “have”, “may have”, “include”, or “may include” refers to the existence of a corresponding feature (e.g., numeral, function, operation, or constituent element such as component), and does not exclude one or more additional features.

In the present disclosure, the expression “A or B”, “at least one of A or/and B”, or “one or more of A or/and B” may include all possible combinations of the items listed. For example, the expression “A or B”, “at least one of A and B”, or “at least one of A or B” refers to all of (1) including at least one A, (2) including at least one B, or (3) including both at least one A and at least one B.

The expression “a first”, “a second”, “the first”, or “the second” used in various embodiments of the present disclosure may modify various components regardless of the order and/or the importance but does not limit the corresponding components. For example, a first user device and a second user device indicate different user devices although both of them are user devices. For example, a first element may be termed a second element, and similarly, a second element may be termed a first element without departing from the scope of the present disclosure.

It should be understood that when an element (e.g., first element) is referred to as being (operatively or communicatively) “connected,” or “coupled,” to another element (e.g., second element), it may be directly connected or coupled directly to the other element or any other element (e.g., third element) may be interposer between them. In contrast, it may be understood that when an element (e.g., first element) is referred to as being “directly connected,” or “directly coupled” to another element (second element), there are no element (e.g., third element) interposed between them.

The expression “configured to” used in the present disclosure may be exchanged with, for example, “suitable for”, “having the capacity to”, “designed to”, “adapted to”, “made to”, or “capable of” according to the situation. The term “configured to” may not necessarily imply “specifically designed to” in hardware. Alternatively, in some situations, the expression “device configured to” may mean that the device, together with other devices or components, “is able to”. For example, the phrase “processor adapted (or configured) to perform A, B, and C” may mean a dedicated processor (e.g. embedded processor) only for performing the corresponding operations or a generic-purpose processor (e.g., central processing unit (CPU) or application processor (AP)) that can perform the corresponding operations by executing one or more software programs stored in a memory device.

The terms used herein are merely for the purpose of describing particular embodiments and are not intended to limit the scope of other embodiments. As used herein, singular forms may include plural forms as well unless the context clearly indicates otherwise. Unless defined otherwise, all terms used herein, including technical and scientific terms, have the same meaning as those commonly understood by a person skilled in the art to which the present disclosure pertains. Such terms as those defined in a generally used dictionary may be interpreted to have the meanings equal to the contextual meanings in the relevant field of art, and are not to be interpreted to have ideal or excessively formal meanings unless clearly defined in the present disclosure. In some cases, even the term defined in the present disclosure should not be interpreted to exclude embodiments of the present disclosure.
